WATER CLOSET.

To all whom it may concern: 7

Be it known that I, WILLIAM R. FENsoM, a citizen of the United States, residing at Richmond, in the county of Henrico and I State of Virginia, have invented certain new and useful Improvements in. \V'ater Closets, of which thefollowing isa specification. This invention relates to water closets of that type known as frost proof closets, including a pressure tank connected to a source of Water supply and also to a bowl, together with a valve whichjis operated by movement of the seat to control the valve so as to admit water to the tank, and then from the tank to the closet bowl to ilush the latter, the supply'to the tank be ing at the same time closed so that the tank remains empty until the next operation. The apparatus includes a drain for draining the valve casing sothat no water will remain therein, all of the operations being automatically produced by the movement of the closet seat.

the valve structure, especially with respect to its seat, and also withrespect to the control of the drain vent. One of the principal objections incident to this type of closet is that the parts are apt to stick either from the presence of frost or from other causes, and the present invention avoids this objection as will appear from the following description.

One form of the invention is illustrated in the accompanying drawings in which Fig. 1 is a side elevation of the apparatus. Fig. 2 is a vertical section of the valve.

The general mode of operation of this type of closet is quite well understood in the art, and need not be explained in detail,

except as appears below. The tank which holds enough water to flush the bowl at each operation is indicated at 6, the bowl 5 at 7, the seat at 8. The tank is connected by a pipe 9 to a valve casing or stand pipe which includes several sections or members,

one member being a T-fitting 10 to which the pipe 9 is directly connected at the side, 0 the upper end of the fitting being screwed into a casing 11 and the lower end receiving the threaded end of pipe 12 which will be extended below thefrost line and connected to the supply pipe 13 by an interposed valve casing 14, to be more fully described. The

An object of the invention is to improve fitting 10 is believed to be new in this relation and is a matter of considerable importance inasmuch as it may be turned around to any angle so that the pipe line can be connected thereto in. various posi tions, whereby it may be accommodated to local conditions without requiring exact dimensions in the supporting structure or partition, or particular location of the tank. That is, the tank can be set 01f at an angle if necessary. a

The casing 11 is connected by a branch 15 to the bowl to discharge the fiushwater into the same, and this connection has a bracket 16 to which the soat is hinged by means of rearwardly projecting cam arms 17, projecting from a curved plate 18 secured to the under side of the seat. The arms project to proper position to engage under an adjustable flanged nut 19 on the upper end of a valve stem 20, the lower end of which carries a rubber or composition plug valve 21 which closes upwardly against a seat formed around the lower end of an internal sleeve 22 which is set in the upper end of the casing 11, the lower end of the sleeve being tapered to form a ground joint at 23 with the tapered side of the casing 11. The sleeve has a hole 24 which registers with the outlet connection 15, and the sleeve is confined in place by a screw gland and cap 25 which is screwed on the top of the casing 11, a gasket 26 being set between the cap and the top of the sleeve to make a tight joint. When the sleeve is dropped in position it is held in place by the cap pressing down thereon, and a pin 27 may be inserted in notches in the top of the sleeve and the casing so that the sleeve can not turn and" carry the hole 24; out of registrywith the outlet 15. A spring 28 is coiled around the valve stem and tends to hold the valve open, with the seat slightly raised from the bowl.

The stem 20 is connected at its lower end by a fitting 30 to a rod 31 which operates the foot valve, the rod extending thru the pipe 12. The foot valve comprises a plug 32 which closes against a seat 33 at the bottom of the casing 34 and serves to shut off the supply of water below the frost line. The casing 34 has a by-pass 35 at one side thereof, and when the valve 32 is opened, the water will flow thru the bypass and up thru the pipes 12 and 9 to the tank. The valve stem 31 also carries a cut-offvalve or plunger 36 which works across a vent opening 37 connected by a pipe 38 to the soil pipe or trap. hen the foot valve is opened, the plunger 86 closes the port 37. hen the foot valve is closed, the drain port is opened and the water in the pipe is drained off to the sewer.

In operation, when the closet is used, the seat is depressed. This lifts and closes the head valve 21 and opens the foot valve 32 and the water from the supply main rises into the tank 6 to the extent permitted by the air compressed therein. \Vhen the seat is released, the spring 28 forces the valve stem down, opens the valve 21 and closes the valve 32. The water then trapped in tank 6 is forced by the compressed air and gravity down thru the pipe 9 and thru the valve casing and the bowl connection 15 into the bowl until it is completely discharged, the remaining water escaping thru the drain vent 37. This makes a frost proof. apparatus, the tank and connections remaining empty until the closet is again used.

It will be noted that the construction is such that when the cap 25 is unscrewed, the entire valve and the sleeve 22 can be lifted out of the casing. This makes repairs very easy and simple, and the valve being entirely outside of the bowl, there is nochance for bowl sediment or incrustations to cause sticking of the valves.

I claim:

1. The combination of a valve casing having an inlet connection at its lower end and an outlet at the side and a tapered portion between the lower end and said outlet, a non-threaded sleeve fitting within the casing and having a tapered inner end which fits against the tapered portion of the casing and also having a valve seat at said lower end, and an opening in the side registering with said outlet, a plug valve adapted to close upwardly against the seat, a cap on the upper end of the casing, confining the sleeve in place, and a stem connected to the plug valve and working thru said cap.

2. The combination set forth in claim 1, the sleeve being provided with means to prevent turning thereof in the casing.

In testimony whereof, I afiix my signature.

WILLIAM R. FENSOM.
